China is known greatly in terms of its cultural values over the past few years.
A. to change
B. having changed
C. changing
D. to have changed

A. to changeB. having changedC. changing(答案→)D. to have changed解析：句意：大家都知道在过去的几年里面，中国就文化价值方面大大改变了。这里使用了Sb/Sth is known to have done 的句型，因为是over the past few years，所以change这个动作已经发生了，用不定式的完成式，选D。

这个解释是对的
